Instant DNA Analysis on a Chip
University of Virginia professor James Landers has reduced an entire laboratory for DNA analysis to a chip the size of a common everyday microscope
slide. What would be the usages for such a credit-card-sized-system? Such a device could be used in a doctor's office, for example, to quickly test
for an array of infectious diseases, such as anthrax, avian flu or HIV, as well as for cancer or genetic defects. Because of the quick turnaround
time, a patient would be able to wait only a short time onsite for a diagnosis. Appropriate treatment, if needed, could begin immediately. Currently,
test tube-size fluid samples are sent to external labs for analysis, usually requiring a 24- to 48-hour wait for a result. However, when it involves
an infectious disease such as meningitis, time is of the essence. Landers said. "We can greatly reduce that test time, and reduce the anxiety a
patient experiences while waiting."
This DNA chip may allow physicians, crime scene investigators, pharmacists, even the general public, to quickly and inexpensively conduct DNA tests
from almost anywhere, without need for a complex and expensive central laboratory. Landers said that with his a lab-on-a-chip, it takes just 30
minutes to do the work it would take three technicians and three instruments to complete in a week. It would also simplify genetic testing and the
work of crime scene investigators. They could collect and analyze even a tiny sample of blood or semen on the scene, enter the finding into a genetic
database, and possibly identify the perpetrator very shortly after a crime has occurred. Likewise, agricultural biotechnologists could do very rapid
genetic analysis on thousands of hybrid plants that have desirable properties such as drought and disease resistance. Landers comments "we can now do
lab work in volumes that are thousands of times smaller than would normally be used in a regular lab set-up, and can do it up to 100 times faster. As
we improve our techniques and capabilities, the costs of fabricating these micro-analysis devices will drop enough to employ them routinely in a wide
variety of settings."
